To (til whom it may concern."

Be it known that I, PHILANDER J. Davis,

roe and State of New York, have invented a certain new and useful Vulcanizing Appara tus, of which the following is aspecification,

reference being had to the accompanying drawings, in which- Figure 1 is a front elevation of my device. Fig. 2 is an end elevation seen from the lefthand side of Fig. 1. tion seen from the right-hand side of Fig. 1, and Fig. at is a front elevation of my device with the cover removed.

The object of my invention is to produce a vulcanizing apparatus in which the fastening devices for the cover of the retort are easily managed, easily adjustable to provide for compression of the packing and'totake up wear, and are all fastened togetherso that 1 accomplish these objects by the devices hereinafter described and claimed.

In the drawings, A is the retort, whose edge only is directly visible, but which is shown mainly in dotted lines in the respective views.

A is the support for the retort and the cover operating devices, within which is placed the source of heatfor producing the Upon the support A rests a ring B, provided on opposite sides with the lugs 13 and b. To the lug B is pivoted, at E the clamping-lever D. Into the lug B is screwed or driven a pin B against which the lever D rests when the cover is fully removed from the retort, as shown in Fig. 4. The clamping-lever D eX- tends upward from the lug B, thence over the retort A to a point over the lug 'b. At about the middle of the lever D and at a point immediatelyover the middle of the cover E there is a depending lug D. The cover E is perforated for a stem F, to which is fastened a steam-gage f, a safety-valve f, and a blowoff cock f (Shown in Fig. 1, but omitted in the other drawings.) From the cover also extend lugs e, by which the cover is pivoted at e to the lug D of the lever D. To the free end of the lever D are pivoted, at d", a pair of links (Z, to the lower ends of which is Fig. 3 is an end eleva pivoted a handle cl by meansof the bolt 61 Between the links (1 is the cam or eccentric (:1 which is fastened firmly on the pivot d and which is operated by means of the handle 01 also fastened by meansof a yoke end to the pivot 61 outside of the links d. (See Fig. 3.) l The links are set so far apart that the lug b may pass between them, and the cam is so adjusted on the ends of the links that when the handle is depressed, as shown in Figs. 1 and 3, the lever D will be drawn tightly down, and the cover E will be pressed tightly upon the retort A.

a Any suitable packing may be used to make the vulcanizer tight. If the packing becomes compressed in use or the cam becomes worn, it is necessary to provide means for adjustingthe degree to which the cover may be pulled down upon the retort. Into the under side of the lug I) (see Fig. 4) is screwed a plug 5. the lug and above the upper side thereof and is there provided with a slot for a screwdriver or other means of turning it. On turning the screw the enlarged lower end of the plug 1) may be moved upward or downward, and as the cam cl, when brought into the proper position, always presses against the lower end of the plug 1) the degree of movement or pressure of the lever D, and hence of the cover E, upon the retort A is easily and properly adjusted.

On the upper ends of the links (Z are a pair of projections (1 (see Figs. 1 and 4,) and in the end of the lever D are a pair of pins (1 against which the projections 01 may rest. If the parts are in the position shown in Fig. 1, on raising the handle d the cam is turned, and thereby the links at are released from the pulled around the pivotal point 01, so that the projections d strike against the pins 01 and on further raising the handle the cover E is lifted from the retort A, and the whole device may be swung about the pivot 13? until the pin 13 checks the movement of the lever D, and all the parts may rest in the position shown in Fig. 4 with the retort wide open. It will be seen that one hand only is required for opening the retort and that there are no nuts, bolts, or other parts to The screw passes entirely through lug I). Still lifting the handle, the links are and provided With an operating-handle, and a swinging connection permanently attached to said cam and to the free end ing-lever, whereby the cover unlocked and is lifted and ating the handle only.

2. In a vulcanizing apparatus a retort A,

of said clampis locked and replaced by opera cover E, a support for the retort provided with a ring B on Which the retort rests having lugs as B and b on opposite sides thereof, a clamping-lever D pivoted to the lug B and pivoted at or near its middle to the cover E, a cam d" attached by the links d to the free end of the lever D and arranged to engage the lower side of the lug b, an adjustable plug Z) extending through said lug Z) and whereon the cam 61 presses, and a handle d for operating said cam, whereby the cover is locked and unlocked and replaced by operating the handle only.
